Over a week ago (on r-help, my bad!) I raised a question of why the ubuntu install instructions https://cran.r-project.org/bin/linux/ubuntu/README.html instruct users with a xenial-based system to use deb https://cloud.r-project.org/bin/linux/ubuntu xenial-cran40/ Looking at https://cloud.r-project.org/bin/linux/ubuntu/ there is no xenial-cran40 directory. However, https://cran.r-project.org/bin/linux/ubuntu/ does have this directory, and I managed to update a machine still running Linux Mint 18.3 by putting in deb https://cran.r-project.org/bin/linux/ubuntu xenial-cran40/ I suspect novice users might not have found this work-around, and it was only by chance I found it. My query: Is it intended that xenial support will not be available for R 4.0? Or is this this just an oversight? Or some quirk that affects just my environment? I've tried to ensure caches are updated. Side-bar: I would update the example machine, but it runs some software needed for another use-case that is not working at all on more modern systems. Where possible, I try to keep up to date, and am migrating the use-case over time to a different software environment. Best, JN

CRAN syncs with my server for the Ubuntu directory, which both have the xenial-cran40 directory. So it appears that whomever maintains cloud.r-project.org has not enabled that directory to be synced. I will into that. I have every intention of supporting Xenial for as long as R still builds against it. Michael
For the record, I had exactly the same experience as Prof. Nash on my Ubuntu 16.04 system. Same problem. Same solution.
